G TIG FOR OWSfiA ES 'Lee 0.-=Wiese, Perry, :Iowa Application petober lalfllq,.fierial NO, 1225278 I ting torch or tool, for severing from'the share worn point and cutting edge, for the purpose o f substituting new parts.

The object of my invention is to providea markin "gageihat may be easily and q'uigk'ly vapplied to plow shares of difierent shapes :and sizes witha comparatively small amount of ads justment, and when so applied provide means whereby lines may be drawn on the shareprop erly located and positioned relative 'to the back edge of the share, to Serve as cutting guides for the removal'of worn portions of the share, where- 'by new replacement parts may be easily and quickly placed in properpperative positions 'to be fixed to the share by welding eveniff theshare has been'badly worn; More specifically, it'i's the object ofmy invention to-provide amarkinfg gage having a portion adapted to be 'supportedonthe upper face of the forward .edgeof *the share, by means of which a line may be drawn substantially parallel with the back-edge of thes'hare and near its cutting-edgeand a second marking y por tion; adjustably mounted to the first "marking portion, adapted to rest against the outer "surface of the upper-edge or" the land side of the share by means of which a line may be drawn on the land side near its upper ed whereby the gage may lie-easily and quickly applied to shares having land sides mounted in planes at various angles relative to its cutting edge.

My invention consists in the' construction, ar-

rangement and combination of -the-various;parts of the device'whereby the objects contemplated and attained-as hereinafter'more fully 'set forth,

pointed out in m claims and illustrated in the accompanying drawings, in which:

The dotted lines M; lfi- -lfi-and I'T represent the end :of ai'.e;- p aceme t point to --be applied after the worn parts have been removed. The 'lines 1118, 13,220 and 21 of Figure 5 are :to' be followed byia cutting tore-h for the removal-ofthe worn parts A 2 and 13,- the share then having the form illustrated Figure Plow shares in common us'e are made-in several lengths, the landsid'e portions vvof which are also set at whens angles relative -:to :the back edge of the share.

My improved marking gage comprises an element 22 adapted to be mounted adjacent :to :the outsideface of th lands'ide H to providearguide for drawing the'iines 2'0 :and 2!; and a second 'elment' 23 for 411 aw-ing th 1ineS 18, 1-9 and 24. The element 22 comprises an angular plate having'a fiang e 26' adapted to be placed against the outer surface of the land'side H and a flange 21 to rest-on top of -theladjacerit end :of the share body, as illustrated in Figure 2, said element being curved downwardly at its center to fit the contour of 'the'upper edge of the landside of la 173110? between the edge 29 and the under surface of thenierr'iloer 2? lcleirig 'egualtothe thickness ;of th b ck flan 0 th 'rs ei nt t :b a e .andr pr' i egte q t e dg e li es an 9 lii s efl- Whe the e'lmen f ii apnl ed't p q .shar sham qim tandardlen h the pac end I .7 l 'ofgtheelem nti a msted in si qn e e wi h the b ek.eqe lqrthes a butlw e r to sharesh'aving shorter points, the ,jeleme is ad usted w th the lame: a inst tn 'baked 2 Ti .i a .01 ,r te =9r a sp ing 53 th .rln end o which is fixed to the body of the member '21, the

j'ecting plate 36 the lower edge 31 of which provides a guide for drawing the line l9. Pivotal-1y mounted in the plate 36 is one end of a rod 35 the inner portion of which is slightly curved at 38, the outer end of the curve terminating in a straight portion 39 adapted to be mounted substantially parallel with the back edge of the share, the back end of the rod 35 is provided with a rearwardly and inwardly extending portion 46 having a hook 4| at its back end to serve as a stop to engage the back edge of the share to support the rod 35 at the proper distance from the back edge of the share body. A sleeve 42 is rotatably mounted on the back end of the member 46 to serve as a stop when the gage is applied to shares having short points. The front end of the sleeve 42 has a lug 43 to be turned downwardly when used as a stop and at the time the pin 32 is used as a stop. A brace 44 is provided for stiffening the member 40. The plate -36-is formed with an opening 45 for pivotally receiving the inner end of the rod 35 at times when the gage is used to draw lines for short points.

The use and application of my gage is simple, the worn plow share is placed on a suitable surface plate or table; if the share is one having a long point the angular element 22 is placed on adjacent to the vertical outervertical face of the landside and with the back end of the flange 21 held firmly on top of the landside portion of the share and with its back end even with the back edge of the share. The hook 39 is then placed over the back edge of the share with the rod 35 adjacent to the upper face of the share near its front edge. A line 18 may then be drawn alo either the front or back side of the rod 35 by means of chalk or any other suitable instrument. A line may then be drawn alOIlg the front edge 31 of the plate 35, lines 24, 2| and 26 may then be drawn along the front end of the member 21 and along the edge 29 of the member 26.

If the gage is to be applied to a share having a v .short point the inner end of the rod 35 is inserted in the opening 45, the sleeve 42 is then rotated to move the lug 43 to extend downwardly, the pin 32 is also pressed down through the hole 34, the gage is then placed in position as before described with the lug 43 and the pin 32 against different angle relative to the back edge of the share than that of another share.

By forming the under surface of the flange 21 to the same contour as that of the top edge of a share before it has been worn means is provided for accurately drawing the line 20 regardless of the amount the point and the upper edge of the landside portion has been worn, since the forward end of the member 22 is supported to the proper elevation by the back end being held firmly on the unworn portion of the upper edge of the landside portion, as shown in Figure 3.

Thus it will be seen that I have provided a marking gage for worn plow shares of simple, durable and inexpensive construction which may be easily .top of the landside portion with the flange 26 V 4 and quickly applied and when so applied provide means whereby both the cutting edge and the forward end of the landside portion may be marked with one setting of the gage.

I claim:

1. A gage to serve as a guide for marking a worn plow share and its landside portion to provide lines for the removal of its worn point and cutting edge, comprising, a substantially horizontal and elongated body including front and back ends, inside and outside edges, the inside edge including an extension having a forwardly and inwardly inclined marking edge, the outer edge .of said body terminating in a downwardly extending flange, a marking rod having one end pivoted to said extension to swing in a substantially horizontal plane, the free end of said rod having a rearwardly extending extension.

2.

3. A gage to serve as a guide for marking a worn plow share and its landside portion to provide lines for the removal of its worn point and cutting edge, comprising, an elongated body including back and front ends also inside and outside edges, the outside edge having a downwardly extending flange, the inner edge including a forwardly and inwardly inclined extension provided with a plurality of pivot openings, a marker rod having one end adapted to be pivotally mounted many of said openings, the other end of said rod terminating in a rearwardly extending portion, a stop device supported by the free end of said portion, and a movable stop device mounted on and near the back end of said elongated body, said body being adapted to be placed on the upper surface of the landside portion of a plow share with its stop device engaging the back edge of a plow share, with its front edge terminating near the point end of the share and with the downwardly extending flange adjoining the landside of the share for locating the elements of the gage whereby, the lower edge of the front end of said flange, the front end of said body, the front edge of said inclined extension and said rod will serve as marking guides.
